[0002] A mold ejector pin, also known as a slanted ejector, is a mechanism used in mold design to form the internal undercut of a product. Because the undercut surface requires a high degree of roughness, it needs to be ultra-precision machined.
[0003] Current mold tilting ejector replacement technology has several drawbacks: Traditional tilting ejector ultra-precision tooling uses a downward pressing method for fixation, requiring recalibration of machining coordinates and re-establishment of the mold after each piece is completed. This repetitive preparation for ultra-precision machining is inefficient. Therefore, there is an urgent need to design a high-precision tooling that allows for rapid tooling changeover to improve ultra-precision machining efficiency. Utility Model Content

[0009] A further technical solution is that the top surface of the locking and positioning device is provided with a flat groove, and the insertion hole adapted to the length of the inclined top is provided in the locking and positioning device along the top surface of the flat groove.
[0010] A further technical solution is that the inclined top includes a radial straight rod and a locking connector, one end of the radial straight rod is connected to the locking connector, and the other end extends into the locking and positioning device through the insertion hole.
[0011] A further technical solution is that a notch is provided on the side of the insertion hole, and the notch communicates with the top of the insertion hole.
[0012] A further technical solution is that at least two support feet are provided, which are symmetrically distributed on the bottom surface of the base plate or all of them are provided on the bottom surface of the base plate directly below the locking and positioning device.

[0028] It should be noted that the base plate 4 can be in the shape of a disc, cuboid, or cube. The plug-in 5 can be a headless screw 7.
[0029] In this embodiment, after the base plate 4 and the locking and positioning device 2 are fixed, the inclined ejector 1 is inserted into the locking and positioning device 2 through the insertion hole 10, and then the plug 5 is inserted into the locking and positioning device 2 from the side, thereby fixing the inclined ejector 1 inside the locking and positioning device 2, which facilitates mold processing. When replacement is needed, the inclined ejector 1 can be quickly replaced by disassembling the plug 5, and then the inclined ejector 1 to be processed can be re-erected, reducing the preparation time before ultra-precision machining, enabling quick model changes, improving efficiency, and solving the technical problem that the existing ultra-precision tooling for the inclined ejector 1 is fixed by pressing down, requiring recalibration of machining coordinates and re-erecting of the mold after each one is completed, resulting in repetitive preparation before ultra-precision machining.
[0030] Preferably, the top surface of the base plate 4 is provided with a first positioning pin 6, which is connected to the bottom of the locking and positioning device 2, and the base plate 4 is provided with a screw 7, which is connected to the locking and positioning device 2.
[0031] In this embodiment, before use, the locking and positioning device 2 and the base plate 4 are positioned by the first positioning pin 6, and the locking and positioning device 2 and the base plate 4 are further fixed by screws 7 passing through the base plate 4, which facilitates subsequent inspection work.
[0032] Preferably, the locking and positioning device 2 has multiple slots 8 on its side that are connected to the insertion hole 10. The slots 8 receive multiple plugs 5, and the plugs 5 extend into the insertion hole 10 and abut against the inclined top 1.
[0033] In this embodiment, the slot 8 is connected to the insertion hole 10 provided in the locking and positioning device 2. When the plug 5 extends into the locking and positioning device 2 through the slot 8, it can contact the inclined top 1, thereby fixing the inclined top 1 and facilitating subsequent stable operation.
[0034] Preferably, the top surface of the locking and positioning device 2 is provided with a flat groove 9, and a plug hole 10 adapted to the length of the inclined top 1 is provided in the locking and positioning device 2 along the top surface of the flat groove 9.
[0035] In this embodiment, the flat groove 9 is located at the top of the locking and positioning device 2, and its smooth surface facilitates the chiseling of the insertion hole. When the inclined top 1 extends into the locking and positioning device 2 through the insertion hole 10, the top of the inclined top 1 can rest on the top surface of the flat groove 9. After the work is completed, the top of the inclined top 1 can be grasped and pulled out of the insertion hole 10, and then the inclined top 1 to be processed can be replaced.
[0036] Preferably, the inclined top 1 includes a radial straight rod 11 and a snap-fit connector 12. One end of the radial straight rod 11 is connected to the snap-fit connector 12, and the other end extends into the locking and positioning device 2 through the insertion hole 10.
[0037] In this embodiment, during use, the radial straight rod 11 is inserted into the locking and positioning device 2 through the insertion hole 10 until its bottom end contacts the inside of the locking and positioning device 2 and then stops. At the same time, the snap-fit connector 12 snaps into the top surface of the flat groove 9. Then, the plug 5 is inserted from the side of the locking and positioning device 2 and abuts against the radial straight rod 11 to stabilize the radial straight rod 11 inside the locking and positioning device 2.
[0038] Preferably, a notch 14 is provided on the side of the insertion hole 10, and the notch 14 communicates with the top of the insertion hole 10.
[0039] In this embodiment, the notch 14 design facilitates the radial straight rod 11 to extend into the locking and positioning device 2 through the insertion hole 10, and also facilitates the subsequent machining of the inclined top 1.
[0040] Preferably, at least two support feet 13 are provided, which are symmetrically distributed on the bottom surface of the base plate 4 or are all provided on the bottom surface of the base plate 4 directly below the locking and positioning device 2.
[0041] In this embodiment, multiple support feet 13 are used to support the base plate 4. The support feet 13 can be symmetrically arranged on both sides of the base plate 4 to improve the stability of the base plate 4. Alternatively, all the support feet 13 can be arranged on the side of the base plate 4, directly opposite the locking and positioning device 2, which also improves the stability of the base plate 4.
[0042] Preferably, the top surface of the base plate 4 is provided with a locking and positioning device 2 and a counterweight 3, and the counterweight 3 and the locking and positioning device 2 are in weight balance.
[0043] In this embodiment, during the processing, in order to ensure the stable operation of the locking and positioning device 2, a counterweight 3 can be placed on the top surface of the base plate 4 to balance the lateral gravity of the locking and positioning device 2 and prevent the locking and positioning device 2 from tipping over during operation.
[0044] Preferably, the bottom surface of the counterweight 3 and the top surface of the base plate 4 are connected by a second positioning pin.
[0045] In this embodiment, the counterweight 3 and the base plate 1 are positioned and connected by the second positioning pin, so that the counterweight 3 can be flexibly disassembled and can also play a role in gravity balance.
[0046] Preferably, the locking and positioning device 2 includes a polyhedron, and the top of the polyhedron is provided with a plug hole 10.
[0047] In this embodiment, the locking and positioning device 2 is designed as a polyhedron, and its high positioning accuracy is ensured by using external positioning line cutting for actual fit.
